Lauren Rathmell and Mohamed Hage co-founded Lufa Farms in Montreal in 2009. The company has four urban gardens in the Canadian city, all in rooftop greenhouses. Lufa’s most recent sits on top of a former warehouse and measures more than 15,000m2 – larger than the other three greenhouses combined. Its main crops are tomatoes and aubergines, producing more than 11,000kg of food per week. It is, the company says, the largest rooftop greenhouse in the world.

Lufa Farms opens world's largest commercial rooftop greenhouse.

Lufa’s first greenhouse was opened in 2011, in Montreal’s Ahuntsic-Cartierville borough, to grow herbs, microgreens, cucumbers and peppers. Two more were added in 2013 and 2017, with the fourth joining in 2020. It sits on top of a former Sears warehouse in the Saint-Laurent area of the city. Lufa rely on Argus Controls in their facilities to help their environmental control and automation needs and to achieve consistent and repeatable results.
